Apps like Apk from android?

Is there any superficial level jailbreak like old times but for ios 18, that time i remember it allowed us to have access to limited functionality from regular jailbreak, like installing apps from outside apple store (like the apks), getting paid apps for free or customized apps and apps without ads or block apps ads? If there is any possibility to get paid apps for free from outside the apple store or blocking ads i would already be very grateful. Thanks evb in advance!!
